Overview：
Hanakiyo is a woman with an estranged son who was divorced due to her husband's violence. Tired from daily life,she comes on a trip to a hot spring where a man working there turns out to be her long-lost son,Takashi. At first,Hanakiyo doesn't recognize Takashi,but along the way,Takashi confesses his true identity. Takashi resents his mother for abandoning him,saying,"I can't see you as a mother now. My life has been a mess because you abandoned me. Even at this age,I still don't know about women... If you're going to play mother,then teach me about women." Hanakiyo offers her body to Takeshi,who has not had sex in a long time,and it makes him feel good. Takeshi then presses his mother for a relationship,and so the sordid relationship between mother and son begins.
